In the year 1741, the Marathas invaded Tiruchirapalli and took Chanda Saheb as captive. However, Chanda Saheb was able to secure freedom in the year 1748, and soon got involved in the Great War for the Nawab`s place in the Carnatic against Anwardeen, the Nawab of Arcot and his son Mohammed Ali. Mohamed Ali annexed the two palayams of Udayarpalayam and Ariyalur situated within the present district of Ariyalur on the grounds of default in payment of tributes and failure to help him in suppressing the rebellion of Yusuf Khan. In the month of November 1764, Mohamed Ali represented the issue to Madras Council and received military assistance on the 3rd of January 1765. The forces led by Donald Campbell and Umdat-Ul-Umara entered Ariyalur and captured it and the young Poligar with his followers escaped to Udayarpalayam. On the 19th of January, the army marched towards Udayarpalayam. The troops of Poligar were defeated and the palayams were occupied. The two poligars fled away and took refuge in Tharangampadi, which was then a Danish settlement. The annexation of the palayam gave the Navab an undisputed possession of all his territories extending Arcot to Tiruchirappalli.
